摘要： Platinum(II) complexes and the use of these complexes for oxidation of methane to methyl sulfate are disclosed, the catalyst having, as ligands, a network based on aromatic N-heterocycles which has at least 2 coordinative nitrogen atoms per platinum atom, and the complex anion is selected from a halide, hydrogensulfate, hydrogensulfite, sulfate, sulfite, methylsulfate, methanol, water, hydroxide, carbon monoxide, hydrogencarbonate and carbonate. The catalyst enables a selective low-temperature oxidation of methane to methyl sulfate or methanol. The catalysts not only exhibit high activity, but can also be removed easily from the reaction mixture and reused over several runs without significant loss of activity.

摘要： A method for the production of plastics containing fillers is disclosed, in which a reactive precursor for the filler is mixed with the polymer precursor, the reactive precursor for the filler is converted into the filler and the polymer precursor is polymerized to form the plastic. The filler generated thus has a particle size in the nanometre range which are evenly distributed in the precursor and also in the finished plastic, such that the appearance of the plastic, for example, the transparency of the finished plastic, is not affected.
